How to test Portal Notification E-Mail

Hi SAP Expert,

Does anyone know, is there a tool or functions in SAP Portal 7.0 that do notification email connectivity testing to the SMTP server.

We just added the configuration in Sys Admin > UME Config > Notifications E-Mail, but haven't seen any mail coming from Portal. We have asked the EMail System admin to check on their side, but one would have thought SAP will think of putting a connectivity test button next to the config screen.
